I definitely rely on the sound change between engraving and cutting, but yes a visual would be a lovely addition!
Of course that would require that the remain connected to the server after the cut starts so it’ll add a layer of difficulty, but if the failure was just that the update was wrong and not that the print job stops running that would be just fine.
It will always be in the last few minutes. If the total will be two hours
engraving will be 95% of the time and the end pat will be worth it. Or you can run the engraving first and without changing anything else put the engrave on ignore and run the cut. I frequently fli[p the cut out piece without moving the rest and just engrave the other side
